No bumble bees on generic wizard?

I'm trying to just come up with possible breeding situations because I may or may not get into breeding these lovely animals but bumble bee isn't on the genetic wizard on world of ball pythons? What does that pair give you so I can maybe move on with my plans?

Only base morphs are featured, a bumblebee is a designer morph (Pastel Spider)

If you use a genetic wizard you will need to select both Pastel and Spider genes.
